Hi y’all! My boyfriend currently has a black 2015 focus that is having some issues! I’ve read a few posts that have helped us with the issue but haven’t exactly told us which part needs replaced! He recently replaced the battery and everything was fine up until a week or so ago. His windshield wipers just started going when he was driving. They were going even when the car was completely off. Then if they weren’t on, they didn’t work at all. We read that the bms needed changed but when we search the part two different kinds show up. Any help on which part we need or if there’s something else we need to do?
